HENRY HELLWEG, OF MILWAUKEE, WISCONSIN.

. METALLIC SHOE-HEEL.

SPECIFICATION forming part of Letters Patent No. 703,581, dated July 1, 1902.

Application filed October 28,1901. Serial No. 80,176. (No model.)

To all whom it may concern:

Be it known that I, HENRY HELLWEG, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and-useful Improvements in Metallic Shoe-Heels,of which the following is a specification.

My invention relates to improvements in cast-metal shoe-heels and it pertains more especially, first, to the device for attaching the heel to the shoe, and, second, to the device for attachinga non-metallic tread-piece to the bottom of the heel.

The construction of my invention is explained by reference to the accompanying drawings, in which- Figure 1 represents a longitudinal vertical section. Fig. 2 is a top view. Fig. 3 is a vertical section drawn on line :0 m of Fig. 2, and Fig. 4 is a bottom view.

Like parts are identified by the same reference-letters throughout the several views.

My heel consists of a hollow cast-metal shell A, which is preferably made of aluminium. The fasteningbarbs C and the fastening plates B are formed integral from a single piece of malleable sheet-iron. Two or more of the barbs O are preferably formed in connection with a single fastening-plate. When the barbs and fastening plates are thus formed, they are supported in a mold in such a manner that the molten metal forming the shell of the heel will not only flow around the ends of the fastening-plate, but will also flow around the fastening-plate itself and form a truss D, which truss extends from one side of the shell to the other and serves the twofold purpose of strengthening the walls of the heel and holding said fastening-plates securely in place. The lower end of the heel is also provided with a cast-metal truss E, which is formed integral with the walls of the heel and serves the twofold purpose of supporting the walls of the heel at its lower end andas a means of fastening the tread-piece F to the heel. The truss E is provided with a plurality of screw-threaded apertures G for the reception of the fastening-screws H. The screws H are of novel construction in this respect: that they are each provided with a screw threaded central portion I and two pointed ends J. It will be understood that the several screws H are secured in the apertures G preparatory to attaching the tread-piece. The several screws being in place, the heel is placed upon the tread-piece, when the heel is forced ordriven down upon said tread-piece until the ends J of the screws H are forced through the same. This being done, the protruding pointed ends J are turned over and clenched down upon the under side of the tread-piece, as indicated in Fig. 4, whereby said tread-piece is held firmly and securely in place.

When the heel has been completed, it is secured to the sole or bottom of the shoe by the fastening barbs O, which are forced through the sole or bottom of the shoe in the ordinary manner by the application of pressure. The inner ends of said barbs are then turned over and clenched upon the upper side of the sole, whereby said heel is held rigidly and securely in place. Owing to the fact that the tread-piece of the heel will frequently become worn away before the heel or other parts of the shoe are worn out it becomesnecessary to replace the same with another. It therefore becomes important to provide each pair of shoes with the necessary screws for fastening said extra tread-piece,

and especially so where fastening-screws of the required size or make are not easily procured. To overcome this objection, I have provided each fastening-screw with the double-pointed ends J, whereby when the worn tread-piece is removed said fastening-screws may be withdrawn and reversed in their fastening-holes, so that their opposite ends may be used for fastening the new tread-piece with the heels.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. As a new manufacture, a shoe-heel comprising a cast-metal shell, provided with a plurality of transverse strengthening-trusses cast integral with, and connecting, the opposing walls of said shell; malleable fasteningplates, provided with a plurality of fastening-barbs, formed integral therewith, embedded at their ends in said walls, and throughout their lengths in said trusses, as set forth.

2. As a new manufacture, a shoe-heel comprising a cast-metal shell, provided with a said apertures; and a nonmetallic treadpiece secured to the heel by said screws, all substantially as and for the purpose specified.

In testimony whereof I affix my signature in the presence of two witnesses.

HENRY HELLWEG.
